    Anyone else noticing a recent increase in failed Illumina Read 2 Resynthesis?

    Hi All,
    My company has been noticing an increase in failures of our Illumina HiSeq sequencing runs specifically in the 2nd read coming out of read 2 resynthesis. It seems that the intensities and the Q30 scores are plummeting right out of the gate after adding the read 2 reagents. We thought it was because the HiSeq uses RMX enzyme which is less stable than the MiSeq RMR enzyme but we have since replaced the RMX with RMR and are still encountering this issue. Has anyone else been experiencing this Illumina run failure type recently or is it just us?
    Thanks!

      Failing read2

      Hi Sawili2, Just wondering if and how you resolved the issue. I'm having a same problem recently. HiSeq 2000, single indexed, paired-end sequencing with read2 intensity and Q30 plummeting while read1 seem to be normal.

        16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
        by SEQadmin2




        NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
